Skinny outfits

I love Marine's super simple workout gear. Any idea where to get shirts like that? I know it looks really plain and simple but I just went shopping for workout gear in the city and did not see this kind of loose shirts during the first browse. I guess H&M or so stocks something like this in their nightwear section but the quality is so bad that a few washes will ruin it.

The deep v-neck. I just saw a beautiful skinny in a deep v-neck shirt and high-waist skirt and now I'm obsessed. It looked so good with her collarbones and xylo showing, without being vulgar (the way a larger chested women would appear). I think to really work, the fabric needs to be heavier and more structured than a regular tee.

What a coincidence - her IG handle is the EXACT sound I made when I saw that picture!
